A fluid is passed through pores in an electrically insulating membrane. Arranged on the membrane (10a-2,20) are conductive layers (22a 22b), which , are interrupted at the pores. Between the two layers a voltage is applied. The fluid to be treated enters the apparatus by inlet (16) and leaves it by outlet (18). The fluid contains microorganisms or more in general cell material. The voltage is at least so high that a cell wall of the microorganisms is deactivated (for instance perforated) while they flow through the pores.

Why it's free to use
- Filed September 6, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended September 6, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 6, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
